The head of the side rotary type can be converted in seconds to CW,
CCW, or both-way operation. Follow the procedures on the right hand
side for conversion (not applicable to the Maintained, Sequential
Operating, Center Neutral Operating Switches).

Procedures
Lighting Mode Selection of Indicators (SPDT only)
The lighting mode of the operation indicator can be changed easily
between two modes: lighting when the Switch is operating and
lighting when the Switch is not operating.
*1. The lamp is lit when the actuator is at the free position.
*2. The lamp is lit when the contacts have been released and snapped only from
